M. Andrew Johnston Research Collection

The M. Andrew Johnston Research Collection is comprised primarily of beetles, especially darkling beetles (family Tenebrionidae Latreille, 1802). The MAJC has an emphasis on specimens from the southwestern deserts of North America and others pertaining to ongoing systematic research. The collection contains roughly 20,000 pinned specimens, a frozen tissue collection stored in ethanol, and full body disarticulations for morphological examination.M·安德鲁·约翰斯顿研究馆藏以甲虫类标本为核心馆藏，尤其侧重拟步甲科（Tenebrionidae Latreille, 1802）的拟步甲类群。该馆藏（MAJC）重点收藏北美西南沙漠地区的标本，以及与当前进行中的系统学研究相关的其他标本。馆藏共包含约20000头针插标本、一套以乙醇保存的冰冻组织标本，以及用于形态学检视的完整躯体解离标本。
